---------------------------------------------
will it be easy for you t add that particular test to the unit test? The reason I am asking
is because this patch actually removes an non-relevant unit test; if it could instead replace
it by a relevant unit test, that will be great. Thanks.

> Currently, if a source file has a replication factor lower or equal to that expected
by RAID, the file is skipped and no parity file is generated. I don't think this is a good
behavior since parity files can get wrongly deleted, leaving the source file with a low replication
factor. In that case, raid should be able to recreate the parity file.
